on

BEIJING, Nov. 8, 2024 /PRNewswire/ — WiMi Hologram Cloud Inc. (NASDAQ: WiMi) (“WiMi” or the “Company”), a leading global Hologram Augmented Reality (“AR”) Technology provider, today announced the initiation of exploring the integration of Reinforcement Learning (RL) into the federated learning framework. RL, as a significant branch of machine learning, has become a crucial tool for optimizing the federated learning process due to its decision-making capabilities in complex environments.

Reinforcement Learning is a machine learning approach that enables an intelligent agent to learn optimal strategies through interactions with the environment. In a blockchain-based federated learning framework utilizing reinforcement learning, the reinforcement learning algorithm can dynamically adjust the timing of model aggregation, selection of data participants, and transaction costs. This achieves a balance between information timeliness and data bias, as well as intelligent control over transaction costs, ultimately optimizing the overall learning performance.

In federated learning, there can be significant differences in the datasets of different participants, known as the data bias problem. Additionally, model updates need to be aggregated at the appropriate timing to avoid outdated information affecting overall learning performance. The reinforcement learning algorithm can simulate interactions with the environment to learn when to upload model updates and how to select the most effective models for aggregation under different data distributions. This helps find the optimal balance between information timeliness and data bias. The cost of blockchain transactions, including the consumption of computational resources and network bandwidth, is another important consideration in federated learning. Reinforcement learning can intelligently predict network conditions, resource availability, and transaction priorities to dynamically adjust the frequency and scale of model aggregation. This ensures learning effectiveness while minimizing overall transaction costs. By applying reinforcement learning algorithms to optimize model aggregation strategies, not only does it significantly improve federated learning efficiency and model accuracy, but it also effectively reduces transaction costs.

With the continuous advancement of technology, blockchain-based federated learning frameworks based on reinforcement learning will play a crucial role in various fields such as healthcare, financial services, and the Internet of Things (IoT), promoting the security, efficiency, and widespread adoption of artificial intelligence technology. For example, in the healthcare industry, this framework can facilitate data sharing among hospitals, research institutions, and patients, accelerating the development of disease diagnosis and treatment plans while strictly protecting individual privacy. In the financial services industry, it can assist banks and financial institutions in building more secure and efficient credit assessment and risk management models. In the field of IoT, it enables intelligent collaboration among devices, enhancing the overall network’s responsiveness and intelligence level.

WiMi’s research on the blockchain-based federated learning framework using reinforcement learning represents a significant innovation at the intersection of artificial intelligence, blockchain technology, and reinforcement learning. It provides innovative approaches to address the trust, security, and efficiency issues faced by traditional federated learning. In the future, with further theoretical research and practical applications, the technological potential of blockchain-based federated learning using reinforcement learning will be more fully explored and widely applied in various industry sectors.

XCMG XCA4000 Achieves Milestone with Installation of World’s Tallest Hybrid Tower Wind Turbine

Published

on

By

ORDOS, China, Dec. 26, 2024 /PRNewswire/ — A new chapter in green energy is unfolding in Inner Mongolia as XCMG’s independently developed 4,000-ton all-terrain crane, the XCA4000, takes center stage at the construction site of the Ordos Zero-Carbon Industrial Park. This enormous crane has become an integral part of the park’s 500MW integrated wind-solar-storage demonstration project, reinforcing its role in pioneering sustainable infrastructure.

The Ordos Zero-Carbon Industrial Park is a joint venture between the Ordos Municipal Government and Envision Technology Group, and stands as the world’s first fully operational zero-carbon industrial zone. It boasts a 100% green electricity supply, with 80% of the energy coming directly from clean sources such as wind, solar, and storage, and the remaining 20% sourced through grid-purchased green power.

The introduction of XCMG’s 4,000-ton crane marks a significant milestone in global energy transition. The XCA4000 is designed primarily for the installation of large wind turbines with hub heights of up to 190 meters tall and maximum power output of up to 15 MW. Powering the crane is a 566 kW Weichai diesel engine, and to help with maneuverability, all 11 axles on the 29.7-meter-long carrier are steered, with eight of them also driven. 

In its most recent operation, the XCA4000 lifted a 117-ton nacelle and drive train, along with 35-ton blades measuring 118 meters in length, to a height of 190 meters—the equivalent of a 60-story building. The XCA4000 performed flawlessly in executing each step of the process: lifting, rotating, aligning, and positioning, with remarkable efficiency and precision, earning acclaim from both the project owner and contractors.

“The 4,000-ton crane is easy to operate despite its 11-axle length,” said Mr. Yang, the crane’s operator who marveled at the crane’s flexible steering. “The multiple driving modes make steering exceptionally flexible. During installation of a 12.5 MW hybrid tower wind turbine, currently the tallest on land, it completed the two lifts in just over twenty minutes each.”

XCMG’s 4,000-ton crane is a testament to the company’s commitment to high-end, intelligent, and green solutions that serve the international market. By tackling the challenges of installing ultra-high-power wind turbines, XCMG continues to support the growing global green energy sector and demonstrates China’s dedication to environmental progress.
